Trouble Shooting HVAC

AC Repair Boise -Trouble shooting HVAC – To help trouble shoot an ac repair Boise is a bit harder since most ac units do not have diagnosis lights.  However there are still a few things you can look for.  First check the thermostat settings and the main breaker for the a/c unit.  Next with the stat turned on see if the unit outside is running, if not you may have a blown fuse in the service disconnect next to the unit.  If the unit is running, check the temperature of the air coming out of the top of the a/c unit.  It should be about 30 degrees warmer than the outside air.  If it is not then you have a larger issue at hand.  Also check the large copper line going into the ac unit, this line should be cold to the touch but never have ice on it.  Many times on an ac repair we find it is iced up.  Icing will occur when your filter is clogged, indoor fan motor goes bad or if you are low on Freon.  I hope this has helped with your trouble shooting, check our blog for more helpful tips.  Call us for a service call at 208 898-9888.

Thermostats

Honeywell Thermostat – If you have a Honeywell thermostat or any other thermostat and you think it is having issues.  First thing is to check the batteries.  Not all Honeywell thermostats or digital thermostats have batteries but it is a good place to start.  Check the “Fan On” potion of the thermostat to see if that works, also try the other mode (heating or cooling) to see if that function works as well.  If your thermostat is blank check to make sure you have power to your furnace.  The furnace supplies power to thermostats that don’t run on batteries.
